The purpose of this paper is to study large deviations for the solution processes of a stochastic equation incorporated with the effects of nonlocal condition.
Abstract
Purpose
The purpose of this paper is to study large deviations for the solution processes of a stochastic equation incorporated with the effects of nonlocal condition.
Design/methodology/approach
A weak convergence approach is adopted to establish the Laplace principle, which is same as the large deviation principle in a Polish space. The sufficient condition for any family of solutions to satisfy the Laplace principle formulated by Budhiraja and Dupuis is used in this work.
Findings
Freidlin–Wentzell type large deviation principle holds good for the solution processes of the stochastic functional integral equation with nonlocal condition.
Originality/value
The asymptotic exponential decay rate of the solution processes of the considered equation towards its deterministic counterpart can be estimated using the established results.

The purpose of this paper is to find a closed relation for the phase noise of LC oscillators.
Abstract
Purpose
The purpose of this paper is to find a closed relation for the phase noise of LC oscillators.
Design/methodology/approach
The governing equation of oscillators is generally a stochastic nonlinear differential equation. In this paper, a closed relation for the phase noise of LC oscillators was obtained by approximating the I–V characteristic of the oscillator with third-degree polynomials and analyzing its differential equation.
Findings
This relation expresses phase noise directly in terms of circuit parameters, including the sizes of the transistors and the bias. Next, for evaluation, the phase noise of the cross-coupled oscillator without tail current was calculated with the proposed model. In this approach, the obtained equations are expressed independently of technology by combining the obtained phase noise relation and gm/ID method.
Originality/value
A technology-independent method using the gm/ID method and the closed relationship is provided to calculate phase noise.

Abstract
Purpose
The purpose of this paper is to investigate how the power dynamics between the client firm and the supplier firm in the information technology outsourcing (ITO) supplier chain influence the supplier firm's human resource management (HRM) practices, particularly talent retention.
Design/methodology/approach
A multi-case study approach was adopted comprising four supplier firms, three client firms and a total of 53 interviews. The transaction cost economics (TCE) is the theoretical lens that guides the interpretation of our findings.
Findings
The power dynamics between client and supplier firms in the ITO supply chain is one underpinned by TCE theory, characterised by an asymmetric client-dominated, transactional relationship, with the client firms controlling the “why”, the “what”, and the “how” dimensions of their collaboration. This “three-dimensional control” led to high talent turnover in supplier firms, which boomerangs to perpetuate the power dynamic, forming “vicious cycles of talent turnover” in the ITO supplier chain.
Originality/value
No previous study has analysed power dynamics as an external factor on ITO supplier firms' talent retention. The construct of the “three-dimensional-control” offers a framework to study power dynamics in the ITO supplier chain. The study’s framework of the “vicious cycles of talent turnover” is the first that explains the mechanisms through which the power dynamics in the ITO influences supplier's talent retention.

Abstract
Purpose
This paper aims to propose a decision-making framework by investigating the impact of perceived risk and computer self-efficacy on the intention to use online stock trading. Furthermore, it demonstrates the mediation effect of attitude and perceived risk as well as the moderating effect of financial literacy.
Design/methodology/approach
An integration of two popular models, technology acceptance model (TAM) and theory of planned behaviour (TPB), is used to provide a sound theoretical base and enhance the understanding of investors’ behaviour towards online trading platforms. The proposed hypothesised model was examined using structural equation modelling.
Findings
The results obtained from this study indicate that all variables, except subjective norms, had a significant impact on investors’ intention to trade online. Perceived risk was found to be a partial mediator between computer self-efficacy and the intention of investors. Finally, financial literacy was also found as a significant moderator for online trading intention of investors.
Practical implications
This study shows the significance of using the TAM and TPB together to provide a comprehensive understanding of the factors that influence an investor’s behaviour in adopting and using technology for online trading. The hybrid approach of TAM and TPB could be considered for a more nuanced and complete understanding of technology adoption and usage in risky affairs like investment decisions. Again, the significant moderating role of financial literacy provides a lance to look into the scope for improvements in investment decision-makings.
Originality/value
The paper develops an assessment framework for analysing the variables based on the hybrid approach for online trading intention in the context of a developing country.

Abstract
Purpose
This study examines the impact of the Association to Advance Collegiate Schools of Business (AACSB) accreditation on education quality. We discern the prospective influences of AACSB, focusing on shifts in teaching methods and content and assessment procedures.
Design/methodology/approach
Using a case study approach, in-depth interviews are conducted with a Japanese-accredited business school’s faculty members to understand their perceptions of the school’s education-quality issues. The data were thematically analyzed.
Findings
Respondents acknowledged that AACSB accreditation has positively influenced teaching, encouraging active learning and the case method. However, they also indicated that accreditation had a restrictive effect on assessment activities, pushing toward compliance rather than genuine learning evaluation. This dichotomy suggests a need for balancing standard adherence with the flexibility to maintain educational depth and assessment integrity.
Research limitations/implications
Convenience sampling may introduce self-selection bias. Furthermore, the qualitative case study approach does not allow for statistical generalization. However, when combined with existing literature, the findings can be analytically generalized and transferred to other contexts.
Originality/value
We provide insights regarding AACSB accreditation’s impact on business education, encompassing shifts in teaching methods and content and faculty perceptions of assessment. This study enhances the scholarly understanding of business school accreditation and offers guidance to accredited or accreditation-seeking academic institutions.

Abstract
Digital financial inclusion is a need of the recent era in order to flourish the growth of economies as well as businesses and individuals. Thus, varieties of digital technologies are launched to provide ease and leverage to customers’ financial needs. Among the well-known digital technologies, Fintech emerged as a well-known and accepted form of digital technologies. However, the acceptance level is much lower, especially in developing sides of the world like Pakistan where issues related to cyber-security are the major hindrance in the way of digitization and n-tier online payments. However, with a massive youth population, Pakistan also has the opportunity to use Fintech as the major tool for economic and social development. Therefore, this chapter has been written purposely to shed light on the importance, use, and role of Fintech in the growth of developing countries like Pakistan. The purpose is to increase the knowledge of youth about financial technologies especially Fintech so they may embrace their abilities with technological innovation, especially for their financial needs. On the other side, the chapter will also address the lack of research on this emerging trend to diverge the focus of researchers and academicians towards Fintech and its uses, scope, implications, and benefits for developing countries.

Abstract
Purpose
This study is part of a participatory design research project and aims to develop and study pedagogical frameworks and tools for integrating computational thinking (CT) concepts and data science practices into elementary school classrooms.
Design/methodology/approach
This paper describes a pedagogical approach that uses a data science framework the research team developed to assist teachers in providing data science instruction to elementary-aged students. Using phenomenological case study methodology, the authors use classroom observations, student focus groups, video recordings and artifacts to detail ways learners engage in data science practices and understand how they perceive their engagement during activities and learning.
Findings
Findings suggest student engagement in data science is enhanced when data problems are contextualized and connected to students’ lived experiences; data analysis and data-based decision-making is practiced in multiple ways; and students are given choices to communicate patterns, interpret graphs and tell data stories. The authors note challenges students experienced with data practices including conflict between inconsistencies in data patterns and lived experiences and focusing on data visualization appearances versus relationships between variables.
Originality/value
Data science instruction in elementary schools is an understudied, emerging and important area of data science education. Most elementary schools offer limited data science instruction; few elementary schools offer data science curriculum with embedded CT practices integrated across disciplines. This research assists elementary educators in fostering children's data science engagement and agency while developing their ability to reason, visualize and make decisions with data.

Abstract
Here we consider the various ways in which airlines integrate their business activities. The thin markets, long distances, poor infrastructure, and challenging terrain over which many airlines based in developing countries operate can make it difficult to reap the economies of scale, scope, and density that carriers in more developed nations enjoy. There also remain institutional barriers to cross border trade in airline services. As a response to this, airlines from developing regions “cooperate” in a number of ways. This may involve multinational ownership, code sharing, or joint ventures. The rationale for these actions, together with discussion of the outcomes of some of them, is considered here.

Abstract
Purpose
The purpose of this paper is to discuss how enterprises can effectively perceive and use the digital opportunities brought about by digital technologies and dynamic environments and how they can enhance their capabilities to realize digital transformation and adapt to the development of the digital economy era.
Design/methodology/approach
Based on the windows of opportunity theory and strategic cognition theory, this paper conducts an empirical analysis of the questionnaire data of 268 enterprises and discusses the influence of external windows of opportunity and internal windows of opportunity on the digital transformation of enterprises, as well as the action mechanism of strategic cognition and entrepreneurship.
Findings
The results show that both the external windows of opportunity and the internal windows of opportunity have significant positive effects on the digital transformation of enterprises. Strategic cognition plays a partial mediating role in the external windows of opportunity and the internal windows of opportunity influencing the enterprise digital transformation process. Entrepreneurship plays a positive regulatory role in the process of external windows of opportunity and internal windows of opportunity influencing strategic cognition.
Originality/value
This paper deepens the relationship between internal and external windows of opportunity and enterprise digital transformation and contributes a new theoretical cognition. This paper integrates the strategic cognition theory to clarify the complex process mechanism of digital transformation using external situational opportunities and internal capabilities. This paper introduces entrepreneurship into the path mechanism of digital transformation and expands the characteristics of the study of digital transformation antecedents to the individual level within the enterprise.

Abstract
Purpose
Education is widely recognized as a key domain for the promotion of the sustainable development goals (SDGs), prompting an increased focus on sustainable development in foreign language education. Despite increased attention, guidelines about SDGs are often primarily policy-based without concrete guidance, and the integration of education for sustainable development (ESD) within higher education curricula has been slow. This paper aims to mitigate this gap by providing an outline for the curriculum development for three elective English courses integrating SDG themes.
Design/methodology/approach
The paper begins by introducing the SDGs, ESD and its application to language education. From there, this paper outlines three content and language integrated learning courses that integrate global issues into their curriculum. Finally, there is a discussion and consideration of various factors to consider when implementing global issues into an English language classroom.
Findings
Following practical examples of how to integrate global issues into an English language classroom, considerations such as socio-cultural context, teaching context and the expertise of the instructor are discussed.
Originality/value
This paper covers a variety of social topics related to sustainable development in addition to the often addressed environmental topics. Many guidelines about integrating SDGs into education are policy-based without concrete guidance, so this paper aims to provide practical examples and considerations.
